摘要： An optical receptacle that enhances the optical coupling tolerance is disclosed. The optical receptacle of the invention provides, in stead of the coupling fiber installed in a conventional optical receptacle, a glass member with a diameter substantially equal to the diameter of the external fiber. The glass member, which is held by the support, provides a convex surface that abuts against the top of the external ferrule and another surface inclined with the optical axis to prevent the light reflected thereat from returning the optical device. The glass member has a substantially homogeneous distribution in the refractive index thereof; accordingly, the fluctuation in the optical coupling with the external ferrule may be reduced.

摘要： The invention provides a method for manufacturing a optical subassembly even when the assembly involves the positional deviation of the components that induces the discrepancy in the direction of the optical output beam from the optical device. The method first determines the position (x1, y1, z1) of the stub where the optical coupling between the stub and the optical device becomes the maximum. Next, the direction of the optical output beam from the optical device is calculated based on the position above, and, finally, the inclined direction of the end surface of the stub is aligned with the direction of the optical output beam evaluated in the previous step.
